Application filed May 15, 1911. serau ire-627,320.

To all whom it may concert.

Be it known" thatI, Enwano G. MOLINA, residing at East Orange, in the county of Essex and State of New Jersey, have 1nvented certain Improvements in Translating and Registering Apparatus, of which the following is a specification.

My invention relates to what I term the translation of electrical conditions, being especially applicable to the automatic or me.-

chanical selection of line terminals in tele-.

fi forth in my ctr-pending application. Serial No. 312,858,, filed April 20th, 1906.

The accompanying drawings show .diagrammatically successive portions of the system, Figures 1 and 2 representing controlling apparatus including the register and translator, and Fig.5 illustrating selecting apparatus. l

As a particular embodiment of my invention, 'I will describe a partly manual, partly automatic telephone system, in which any. one of ten thousand substation lines may be selected by automatic switches, such as pear at, S, S in Fig. 3 of the drawings,'each' having three hundred triple sets of fixed terminals sand cooperating line brushes s s and a third or test brush 8 The switch S serves as a primary or group selector and the switch S as a final selector or connector, the

former first operating to pick out a non busy final machine in the desired one of the thirty-four groups into which the ten thousand lines are divided. in accordance with the number of terminals in each machine, there being thirty-three groups of three hundrel lineseach, and an additional group of oie hundred lines. These selectors S and S may be of any convenient type, they being illustrated conventionally as each having a shaft 5- carrying thebrushes, and rotatable to move said brushes over the, terminals by.

ratchet'mechanism actuated by motor magnets M and M respectively. Pawls governed by magnets H and H retain the brushes in the-positions to which they are advanced. "A return to normal position upon the deenergization of the magnets H "and H may be effected by suitable spring mechanism. Both switches have oit normal contact devices and the retaining magnets other contact devices, which will hereinafter be designated by reference characters in tracing the circuits.

The apparatus for controlling the action of the selectors includes four sets of manually operable contact devices or keys, K, K, K and K there being ten in each set, corresponding respectively to the digits in the thousands, hundreds, tens and units places of the decimal system of notation, and upon which the numbers designating substation lines may be registered. Each set of keys, which may be spring actuated to hold'their contacts or register elements normally separated, is provided with suitable locking mechanism 7: for the purpose of retaining them when depressed, this locking mechanism being controlled'to bring about the re.- lease of the keys by anelectromagnet K. From what has been said of the arrangement ofthe-substation lines, it will be seen that the dperation of the decimal thousands and decimal hundreds keys must lead to the hon decimal selection of each of thirty-four groups of final selectors, and the further non-decimal selection of a particular hundred of the three in the first thirty-three of these groups. Havingsecured the desired hundred, selection proceeds decimally under the influence of the tens and units keys. To enable this to be accomplished, a translator is associated with the thousands and hundreds keys. This comprises a register switch S having a shaft to which are fixed brushes or contact members 8 a. s and s traveling over fixed terminals or contacts a. 8 s and 5 respectively, under the successive influence of long and short step motor mag- .nets M and M operating appropriate H holds the brushes in position, and springs act to restore them, as in the selectors and other switches hereinafter mentioned. Alt

m l H single or elementary contacts with their intermediate spaces, or a distance covered by ninety-ninesteps of the ratchet mechanism actuated by the motor'magnet 1V. Each of the contacts .9 in the first decimal group is equivalent to ten single contacts, there being ten in all, though here and in other switches of the system, some are omitted. They are consecutively joined by conductors 10 to the thousands'keys K from zero to nine. Each contact 8 of the second decimal group consists of a single contact, and the first ten of these and every'tenth thereafter are multiplied in groups of ten by conductors 11 leading to the respective hun dreds keys K The decimal contacts determine the setting of the register under the.

control of the thousands and hundreds keys.

The primary non-decimal group contacts 8 each includes three of the elementary contacts, except the last, or thirty-fourth, which is single, and from them conductors 12 lead to successive fixed contacts a, thirtyt'ou-r in number, of a selection controlling switch S adaptedto transmit to the selecting apparatus the translated conditions registered. at the bank 8 The brush or contact member a of switch S is caused to travel over the contacts 8 by a motor magnet H and cobperating ratchet mechanism, while a retaining magnet H by the application of a pawl upon its energization, prevents reverse movement. The secondary non-decimal group of single contacts 8 of the register are multipled in three sets by conductors 13, and oined to three contacts 5 of a secondary transmitting switch S",

which is provided with a brush a, a motor magnet hi and a retaining magnet These contacts 5 are separated r'rom one another by distances equivalent to one hundred steps of the switch S under the influence oi? itsmotor mechanism, and determine the i'novement of the selecting apparatus to the beginning of some one of the hundreds in any of the thirty-four primary groups. The non-decimal register terminals, with the cooperating brushes,.thus furnish contact means governing the travel of the transmitting switches and thereby controlling selection under the new grouping. The register and transmitting switches with their retaining magnets operate eXtra contacts, as will hereinafter appear.

Between the tens keys K and units keys 7 and the selecting apparatus, no register oi: the contacts and their connection he keys may be exactly the same as i'nechanisni is interposed, since the terminal the decimal contacts .9 and 8 of the register S The brushes s 8 of the switch, its motor magnet M and retaining magnet H are also similar to those of the register, though it should be noted that the single magnet M causes the advance of the brushes over the entire bank of one hundred contacts in short steps.

Included in the system are relays to vary the circuit connections as may be necessary; these comprise relays R and R at the group and'iinal selectors S and S respectively; a relay R and a sluggish release relay R at the register S a relay R and a sluggish operating relay R? associated with transmitting switch S and a single relay R with switch S while at transmitting switch S is a relay R a sluggish release relay R and a sluggish operating relay R The conductors joining the various sections of apparatus, electromechanisms and elements constituting the system will not be separately described, but will be mentioned in proper order in following'the operation, except it may be said that a calling line may be connected with the selecting apparatus through conductors C, which may be a portion ot a cord circuit, and the normal contacts of a key K manipulated by a central station operator, who also has a release key K and who actuates the digit keys K, K K K in accordance with the number of the called line, some of these lines appearing at L. When the key K* is actuated it dis connects the conductor C from the selecting apparatus and unites the latter to the operators controller through conductors L and L". Electrical energy is supplied to the system by a battery B, which appears atdifferent points-distinguished by different numerals affixed to the reference letter. When intermittent current is desired a pulsator or interrupter I is employed between the battcry and electromechanism to be actuated.

In describing in detail the operation of the system, it will be assumed that the central station operator has received a call for substation line No. 2227. eighth primary group of three hundred lines, said group beginning with No. 2100 and ending with No. 2399. The line of this number is, furthermore, in the second secondary group comprising lines 2200 to 2299,.

and is the twenty-eighth line in said secondary group. Therefore, by the depression of the third thousands key K, the third hundreds key K, the third tens key K and the eighth units key K h'it is necessary to cause the primary selector S to advance its brushes to the ei hth of its thirty-four groups of termib a nals, and the final selector to move its brushes to the beginning of the second hundred of its entire series of three hundred terminals and then to the twenty-eighth terminal therein.

This falls in the By throwing the key K, the operator temporarily associates the primary or group selector S with the controlling apparatus, and the retaining magnet H of said selector is energized lay current flowing from battery B through contact of key K conductor 21 and winding of retaining magnet .11 to ground. The magnet, upbn the attraction of its armature, not only applies the retaining pawl, but also closes a contact which will be of use later in the operation. The operator then depresses the proper digit keys, as previously .indicated, the units key last. Contact 23 of the eighth'units key K closesa-cireuit-from ground through conductor 2-1 and winding of the retaining magnet ll of the :register S to battery B This magnet operates it's pawl; and com pletes at contact a circuit tromground through c mductor 26, winding of the primpry or long step motor magnet M of the ster. conductor 27, back contact :28 of relay R and the interrupter to battery B Each time the magnet is energized by the current impulses, the four brushes of theregister are simultz'ineously driven over ten of the elementary contacts, corresponding to one of the contacts 8 \Vhen two pulses have passed through magnet M relay R is el'icrgized by a circuit from ground thri'mgh contact 29 of the third thousands. digit key K. conductor 10', third thousands terminal a", brush 8", conductor 30 and wind ing of the relay R to battery B lelay R then opens contact 28 and closes contacts 31, 32. The breaking of contact 28 prevents any further transmission of pulses through the winding of magnet M while contact 31. 'auses current to low from the battery B and interrupter through conductor 33, back contact 34 of relay R, conductor Winding of the secondary or short step motor magnet M conductor 26 and contact 25 of retaining magnet H to ground. The opcrat on of motor magnet M continues the movement of the register brushes in short steps from one single contact to another. \Vhcn two pulses have traversed magnet M relay R is energized by the closing ,of a circuit from ground at" contact of the third hundreds digit key K, through conductor 11,'the-twenty-third contact 3 hrusha conductor 36, contact 32 of relay R conductor 37 and windlng of relay R -to battery B RelayR breaks its contact 34 and cuts oil current-from the secondary motor magnet M This movement of the register results in brushes 8, s placing ground'frmn conductor 34' upon the eighthcontact 8- and the twenty-third contact 8 the latter being the second in the eighth multipled groupf The apparatus 1s now ready to control the operation of the. group and final selectors S, S by the translated conditions thus created.

'llelay R besides breaking its back contact 34, makes a front contact 38, thereby energizing retaining magnet ll of the pri-- mary transmitting switch S from battery 13 by way of conductor 39. Magnet H applies its pawl and closes contact all); Pulsatory current will now flow from battery B through the winding of motor magnet M contact lO, conductor 41, back contact 42 of relay R, main lead or conductor L, contact of key Kfiback contact et l of relay R,conductor 45 and winding of the group selector motor magnet M to ground.- Motor magnets M and htloperate in synchronism until eight pulses have been transmitted. The brush 8 of switch S thus arrives at ground placed on the eighth terminal a by brush '8 and thereby establishes two circuits-one through conductor -16 and the winding of relay R to battery B and the other through oil normal contact 47 of the transmitting switch S", conductor 48, back contact 49 to relay R lead L contact-5O of key K conductor 51, normal contact of relay R, winding of said relay, conductor 53, oil normal contacts J-t and of the group selector S and contact of the retaining magnet H to battery 13 lelay R, 'now energized, opens its back contact t). and the circuit of motor magnets h'[ and M and closes contact 56', which energizes the Sluggish operating relay ll from' battery B through conductor 57. Meanwhile relay R disconnects its winding from conductor 51 and locks itself to ground through its front contact 58, conductor 59, brush stof the groufselector ti, the corresponding termiat the brush .9 of the register, while by closing front contact 61 it energizes the restraining magnet H? of the transl'nitting switch S over conductor 62 from battery. B". Magnet Hf then closes contact 63, allowing current impulses to flow from battery B through the winding of motor magnet M of the transmitting switch S, .conductor 64, contact 65 of relay R lead L contact 43 of key- K front contact 66 of relay R, conductor (37, brush .51 of the group selector and corresponding terminal, conducto1.68,'back contact 69 ot relay R eonduotorTO and winding of motor magnet M of the final selector switch to ground. The motor -magnets of the transmitting switchS and final selectorwill now operate synchronously until one hundred and one pulses hare been transmitted. Then there will'be a circuit from the ground at brush 8 of the register, through the twenty-third contact 8 conductor 13, brush a of the transmitting switch 8*, conductor-71 and Winding of relay R to battery B. There'- upon relay R s'evers at contact 65 the circuit of motor magnets M and M and by means of its front contact 72' energizes, by a circuit through conductor 73 from battery B, the retaining magnet H of the transmitting switch S Magnet H by nieans of front contact 74, completes a circuit from battery B and its interrupter,

through back contact 75 of relay R con-.

ductor 76, motor magnet M of switch S conductor 7 7 lead L and then over a path previously traced to ground through the Windin of the final selector motor magnet M otor magnets M and M Will operate together-until twenty-seven pulses have been transmitted. Upon the passage of twenty of said pulses the tens brush 3 will close a circuit from ground at contact '77 of the depressed tens key K through conductor l4, the third terminal 8, brush's", conductor 78 and the winding of sluggish release relay R to battery B. This energizes relay R closingpontacts 79 and 80 in the circult of the units brush 5 When seven more pulses have been transmitted through the motor magnet-s M and M brush 5 reaches the ground placed on the twenty-eighth terminal s by contact 81 of the depressed units -ke K and two circuits are thereby closed y a t from v conductor 82 through contacts 79 of relay R conductor 83 and Winding of 're-,

lay R to battery B and through contact of relay R conductor 84, back contact 85 of sluggish operating relay R ,"conductor .86, lead L contact 50 of key K front contact 87 of relay R, conductor 88, brush s and the eighth terminal group of selector S, conductor 89, normal contact 90 of relay R Winding of said relay, conductor 91, off normal contact 920i the final selector S and contact 93 of the retaining magnet.H to battery B. Relay R in the circuit first traced breaks its back contact .75, thereby opening the circuit of motor magnets M and MK Relay R in the sec- .ond circuit opens its contact 90, thereby disconnecting the Winding of said relay from conductor 89, and closes its front contacts 94, 95, 96. Contact 9a locks the Winding of relay R from battery B to ground by Way of conductor 97, final selector brush 5 and its one hundred and twenty-eighth terminal, test conductor of the selected line L, numbered 2227, and the winding of the Contacts 95 and 96 of usual cutoff relay.

.Q fy

relay R extend conductors 68 and throughconductors 98 and 99 and final selector brushes s and s to the talking conductors of the desired line. 4

Considering again relay R in addition to breakin contact 7 5 it closes contact 100. A circuit is thereby completed from bani-cry the contact members, and sin B for sluggish operating relay R, which is energized, breaking contact 85 and making contact 101. The opening of contact 95 disconnects the grounded units key from lead L Contact 101 closes the circuit of the key release magnets K from battery 13" through conductor l02 unlocking each of the four depressed digit keys, \vhichscparate their contacts. This release of the keys indicates to the operator that the action the controlling apparatus and the. selection of the Wanted line iscomplete." She then reverses the position or" key 11*, which disconnects the controller from the group selector and reestablishes at contactslO?) the circuits between said group selector and the cord conductors C, completing the connection between the calling and called lines. When the contact 23 of the released units key opens, it severs the circuit or" the retaining magnet H of the register switch. Relays R and R fall back upon the loss or the grounds at key contacts 29 and 35, relay R de'e' nergizing the retaining magnet H Switch S and similarly the switches 55* and S Withtheir associated relays, are successively permitted to resume their initial positions. The energization of the retaining magnet H of the group selector, and therefore the retaining magnet of the tinalselector, is maintained by a circuit from battery B through releasing key K At the termination of coi'irersation the operator opens this key, and the selectors S and S successively return to normal, releasing their relays. v
